What are the two dimensions of "publicness" identified by Bozeman? Be prepared to use these two dimensions to compare and contrast different organizations. - ️️1.Economic Authority: Extent to which an organization competes in the marketplace for revenues. - High economic authority = less public - Low economic authority = more public 2.Political Authority - Degree to which an organization is constrained by government rules and regulations - High political authority = more public...

Alkyl halides do one of two things when they react with a nucleophile/base, such as a hydroxide ion... - correct answer (1) undergo SUBSTITUTION of the X group by the nucleophile OR (2) undergo ELIMINATION of HX to yield an alkene carbon-halogen bonds in alkyl halides are polar and the carbon atoms are electron-poor, thus, alkyl halides are ELECTROPHILES Nucleophilic Substitution Reactions - correct answer -each st...
